2 phase flow pump types and manufacturers?

[carltogr]

Does anybody know the best type of pump for 2 phase flow (gas volumes up to 4% in liquid) involving flow rates up to 100 [GPM]? And if so, do you know of any manufacturers?

note: liquid being pumped contains aqueous ammonia and hydrogen peroxide (mostly water.
